CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Community Plant Variety Rights application number 2014/2632, filed Oct. 27, 2014, which is herein incorporated by reference.

LATIN NAME OF THE GENUS AND SPECIES

The Latin name of the genus and species of the novel variety disclosed herein is Vanda Jones ex R. Br.

VARIETY DENOMINATION

The inventive variety of Vanda disclosed herein has been given the variety denomination ‘SPCDW1403’.

BACKGROUND OF THE INVENTION

Parentage: The Vanda variety ‘SPCDW1403’ is the result of a planned breeding program. The new variety originated as a seedling from the crossing of the unpatented, proprietary seed parent Vanda ‘A169’ with the unpatented, proprietary pollen parent referred to as Vanda ‘JBP’. The crossing was made by the inventor in his research greenhouse in Chonburi, Thailand in October of 2002.

The new variety was first selected by the inventor, Thumrong Suphachadiwong, a citizen of Thailand, in April of 2007, in a research greenhouse belonging to the inventor in Chonburi, Thailand. After identifying the new variety as a potentially interesting selection, the inventor continued confidential testing and propagation of ‘SPCDW1403’, assessing stability of the unique characteristics of this variety.

Asexual Reproduction: Asexual reproduction of the new cultivar ‘SPCDW1403’ was first initiated at a commercial laboratory belonging to the inventor in Chonburi, Thailand by tissue culture in April of 2008, with the first mericlones so reproduced flowering in 2013. Access to all plants was restricted, as plants were kept in a greenhouse not open to the public, and tissue culture plantlets were in a laboratory belonging to the inventor, and not accessible to the public. Through subsequent propagation by vegetative cuttings, multiple generations have been reproduced, which have shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘SPCDW1403’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘SPCDW1403’. These characteristics in combination distinguish ‘SPCDW1403’ as a new and distinct Vanda cultivar:

1. Vanda ‘SPCDW1403’ exhibits a light cream-yellow flower; and,

2. Vanda ‘SPCDW1403’ exhibits a unique light brown spotting pattern of the sepals and petals; and,

3. Vanda ‘SPCDW1403’ exhibits strong undulation of both the sepal and petal margins.

BRIEF DESCRIPTION OF THE FIGURES

FIG. 1 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, an exemplary plant of ‘SPCDW1403’ grown in a commercial greenhouse in Honselersdijk, the Netherlands. This plant is approximately 5 years old, shown planted in an 8 by 8 cm container.

FIG. 2 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, the typical foliage of ‘SPCDW1403’.

FIG. 3 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, the typical flowers of ‘SPCDW1403’.

BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements describe a five year-old ‘SPCDW1403’ plant grown in a greenhouse in Honselersdijk, the Netherlands. Temperatures ranged were approximately 23 degrees Celsius during the day and 19 degrees Celsius at night. No photoperiodic or chemical treatments were given to the plants. When natural lighting fell below 150 Watt, artificial lighting is given at 10,000 lux for 16 hours a day.

Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘SPCDW1403’ has not been observed under all possible environmental conditions. Where dimensions, sizes, colors and other characteristics are given, it is to be understood that such characteristics are approximations or averages set forth as accurately as practicable. The phenotype of the variety may differ from the descriptions set forth herein with variations in environmental, climactic and cultural conditions. Color notations are based on The Royal Horticultural Society Colour Chart, The Royal Horticultural Society, London, 2007 (fifth edition).

A botanical description of ‘SPCDW1403’ and comparisons with other varieties of Vanda are provided below.

However ‘SPCDW1403’ differs from the     seed parent in the following characteristics: 1. ‘SPCDW1403’     exhibits a light cream-yellow general tonality of the flower,     whereas ‘A169’ exhibits a brighter yellow general tonality of the     flower. 2. The flowers of ‘SPCDW1403’ exhibit a light brown spotting     pattern, whereas the flowers of ‘A169’ lack said pattern. 3. The     flowers of ‘SPCDW1403’ are smaller than those of ‘A169’. Plants of     the new cultivar ‘SPCDW1403’ are similar to the pollen parent, Vanda     ‘JBP’, in most horticultural characteristics. However ‘SPCDW1403’     differs from the pollen parent in the following characteristics: 1.     ‘SPCDW1403’ exhibits a light cream-yellow general tonality of the     flower, whereas ‘JBP’ exhibits a bright yellow general tonality of     the flower. 2. The flowers of ‘SPCDW1403’ exhibit a light brown     spotting pattern, whereas the flowers of ‘JBP’ exhibits a dark brown     spotting pattern which is more prominent on the flower. 3. The     inflorescence of ‘SPCDW1403’ are significantly shorter than those of     ‘JBP’. -   Comparisons with similar Vanda cultivars known to the inventor:     ‘SPCDW1403’ is similar in many horticultural characteristics to the     commercial variety Vanda ‘SPCDW0510’ (not patented). However     ‘SPCDW1403’ differs from ‘SPCDW0510’ in the following     characteristics: 1. ‘SPCDW1403’ exhibits light cream-yellow general     tonality of the flower, whereas ‘SPCDW0510’ exhibits a brilliant     yellow general tonality of the flower. 2. The flowers of ‘SPCDW1403’     exhibit a light brown spotting pattern, whereas the flowers of     ‘SPCDW0510’ lack said pattern. 3. The sepals of ‘SPCDW1403’ are more     rounded than those of ‘SPCDW0510’. 4. The petal margins of     ‘SPCDW1403’ exhibit a high degree of undulation when compared to the     petal margins of ‘SPCDW0510’. 

That which is claimed is:
 1. A new and distinct variety of Vanda plant named ‘SPCDW1403’, substantially as described and illustrated herein.
